IMPROYEMENTIN HORSESHOE-BLAINK BARS.

Specification formingpart of Letters Patent N 0. 182.535, datedSeptember 26, 1876; application filed May 31, 18 76.

To all whom it may concern Be it known, that I, ALFRED B. SEYMOUR, ofCincinnati, Hamilton county, Ohio, have invented certain new and usefulImprovements in .the Manufacture of Horseshoes, of which the followingis aspecification:

The object of the present invention is to increase the bearing-surfacesof such shoes as are described in Letters Patent No. 167,027, issued tome August 24, 1875.

By referring to this patent it will be noticed that the device describedtherein is furnished with but a single row of calks projecting from themedian line of the shoe, which arrangement, although perfectly reliableand satisfactory for general use, does not afford as extended abearing'surfaoe upon the ground asis desirable in some cases. Therefore,to increase the bearings of the shoe, I duplicate the calks, so as toproduce an outer row and an inner one,

which occupy parallel positions with reference to each other, ashereinafter more fully explained.

My present improvement consists in the production of a blank with twoparallel V- shaped ridges, either sharpened or truncated, formed withtransverse concave depressions, and separated by a longitudinal groove,as hereinafter described.

In the annexed drawing, Figure 1 is a perspective view of the bar fromwhich a horseshoe-blank is to be made. Fig. 2 is another perspectiveview, showing the second step in the manufacture of the blank. Fig. 3 isa plan of a complete shoe, as made from my improved blank. Fig. 4 is alongitudinal section of the same, taken through the valley between thetwo rows of calks. Fig. 5 is an enlarged transverse section of the shoe,and Figs. 6 and 7 represent modifications of my invention.

The first step in the manufacture of my improved horseshoe-blankconsists in rolling a steel or iron bar into the shape shown in Fig. 1,which rolled bar may be of any suitable size. It will be observed thatsaid bar is constructed with a flat under side, A, and a vertical ornearly vertical front edge, B, the inner portion of bottom A beingsomewhat beveled or ohamfered oil at a. The bar or blank isalso'constructed with two V-shaped ridges, splines, or ribs, G 0, whoserespective apices c c are parallel with each other, and in the sameplane." In rolling this bar' the ridges O 0 may be brought to a sharpedge, as seen in Figs. 1 and 2, or said ridges may be truncated, asrepresented at c c" in Figs. 5 and 7. These two parallel ridges areseparated by a groove, valley, or depression, D, having, preferably, theconcave bottom, as represented in Fig. 5, thereby avoiding sharp anglesin the shoe. This ridged and longitudinally-grooved.bar

having been reduced to the previously-de scribed shape, either at asingle operation or by a consecutive series of operations, the finalpass through the rolls channels said blank transversely, so as to removeany desired amount of metal from each of the opposing ridges O C. Fig. 2represents the blank after it has been channeled transversely, theinterdental spaces or notches E being of any suitable length withreference to the standing portions of the ridges, which projectingmembers constitute the calks proper of the shoe.

For the purpose of removing these interdental portions of the ridges Imay employ either a cutter, or press, or punch, or any other device thatwill accomplish the desired result without straining or otherwiseinjuring the bar.

In applying myimproved blank to the manufacture of horseshoes, theblanks are cut into lengths proportionate to the size of shoe desired,after which the bar is reheated and bent around a suitable former ordie, so as to impart to the shoe a shape approximating to the onerepresented in Fig. 3.

By referring to this illustration it will be noticed that the toe-calkis somewhat longer than the other calks, which is my preferred way ofmanufacturing the shoe, although I reserve the right to vary the sizeand numberof projections to suit the demands of trade. After bending theblank the holes F for the nails may be punched through the shoe in anyappropriate place.

It is evident that, by thus providing the shoe with two distinct sets ofcalks, the bearing-surface upon the ground will be increasedaccordingly, and, consequently, the animal will have a more secure holdon a rough and irregular pavement, and be less liable to slip and injurehimself. This duplication of the PATENT DFFICE.

bearing-surfaces enhances the utility of the shoe without addingmaterially to the original cost.

The bar represented in Fig. 2 has the transverse notches E of the tworidges O" and O exactly in line with each other and of correspondingwidth; but this arrangement may be departed from, so as to bring theouter row of calks opposite the transverse channels of the inner row ofcalks. (See Fig. 6.) Fig. 7 shows another modification, in which theridges O C are very much truncated, and the interdental spaces E are cutso as to communicate with each other, by which means the calks aredisposed transversely of the shoe; instead of being arrangedlongitudinally of the same.

I claim as my invention The blank herein described, consisting of a bar,A B, with parallel ridges O G, transverse cavities E E, andalongitudinal separatinggroove, D, as specified.

In testimony of which invention I hereunto set my hand.
